SHOE-SEWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 766,350, dated August 2, 1904.

Application filed l' nuary 14, 1904. Serial No. 188,956. No model.)

To (11/ llf/l/(HH/ it 7111/11 concern:

Be it known that I, CARL HILDEBRANDT, a citizen of Germany, residing at Dusseldorf, Germany, have invented new and useful Improvements in Shoe-Sewing Machines, of which the following is a specification.

This invention relates to a cylinder shoesewing machine, which may also be used for sewing the soles to the uppers.

In the accompanyingdrawings, Figure 1 is a perspective view of the upper part of a shoesewing machine embodying my invention. Fig. 2 is a side view of the machine-head and the parts connected thereto; Fig. 3, a front view thereof; and Fig. 4, a cross-section on line A B, Fig.

The letter represents the feed-dog which is arranged at one side of the needle 5. At its forward end the dog is provided with a laterally-projecting nose a, which extends in front of the needle and is guided along the upper. The needle 7) reciproeates behind the nose and is adapted to pierce the sole as well as the upper.

In order to obtain a reliable guide along the upper and to prevent the latter from being injured, .I employ a guide-bar a, that is interposed between the rear end of the dog f and the upper. This bar is of the same width as the nose (1, or is slightly wider, as illustrated in Fig. 4. The bar .9 is made adjustable, so that by properly setting it the seam can be run at the desired distance from the upper. As represented, the bar is made in the form of an angle-lever, secured at one end ver may be readily swung upward or downward, so as to be withdrawn to the desired extent.

The cylinder it, supporting the work, is subjected to great pressure When the machine is used for sewing soles. To sustain the cylinder and avoid vibration, I pivot to the machine-frame a forked brace t, which is adapted to straddle the cylinder near its free end. "hen the machine is not used for sewing soles, the brace may be swung down to be out of the way.

\Vhat I claim is 1. In a shoe-sewing machine, the combination of a feed-dog having a laterally-extending nose in front of the needle, with a pivoted angular guide-bar engaging the side of the feed-dog and having an inclined slit at the angle, and with a set-screw engaging said slit, substantially as specified.

2. In a shoe-sewing machine. the combination of a cylinder having an overhanging end,

with a forked brace pivoted to the machine frame and adapted to straddle said end, substantially as specified.

Signed by me at Dusseldorf, Germany, this 4th day of January, 1904.
